I often use games on my phone to distract me from my pain. They work better than watching tv or reading books as they seem to engage more proactive areas of my brain, and use up brain power that would otherwise go into processing pain signals.
My latest addiction is Puzzledom. It’s got a large variety of different puzzles. Some of which, I’m already at Expert level, others I’m stuck being a Novice. It’s interesting to me which puzzles I just “get” and which I just can’t seem to manage. There doesn’t seem to be a pattern to it, but I’m sure there is.
The only downside to this app is the amount of ads. There doesn’t seem to be a way to “buy” your way out of seeing them. Luckily most are only 5 seconds long.
So, if your looking for one app that contains a wide variety of puzzles, I’d really recommend Puzzledom.
